useful Improvements in or'Relating to Therino-Electric Generators, (fonwhich I have made application fou -Letters Patent-in France on the th of-October; 1900,'N0.292,723.; in

The present invention relates to a new generator of electricity in which heat is transformed directly into electricity.

The generator consists, first, of a natural mineral of v feldspar origin ,mineral'ogically composed of light particles ofquartz, the particles of which are of the formof small rods or' funicular tubes and is chemically composed of approximately 78.80 "per cent. o silica, 1.44 per cent. jof iron' 'oxid, 6.96 percent. of alumina, 2115.14.32 percent f0)? magnesia, and, second, of zinc or metallic antimony or theiroxids-or their other chemical compounds. Such mineral is quarried at Antogay l'e'Ti-llar par-lee O'rmes, in the-Department of Indre et Loire, France, and consistgmainly, of a mixture of more or less ferruginous clay and of very light particlesofquartz, such as occur in infusorial earth.

The natural mineral and the chosen metal or its chemicalcompound are reducedto a fine powder, mixed and worked together with water, if required,nntil ahomogeneous mass" isohtained, which. can then be' formed into.

bricks, block's,- disks, or the like. The blocks are then dried and afterward placed in an electric furnace, such as is used in theproduction of-calciumcarbid, and here they are exposed to the temperatureflof the electric arcfor several hours, so as to attain the ternperature nearest .to the fusion of the metal or of the oxidem'ployed "in order to. obtain the. molecular combination of .the elements. The mineral thus fertilized or treated may be cut intob'rick's, cylinders, and other suitable shapes, which when heated at one end by any heatsource remain cold or. almost cold at their opposite fonds. If each endis tracto'ry' material,

connected "to a platinu mwireoraiterminal-of a circuit, an -electricfcu rr e'ntwill fiowthrough the circuitd,uringallthe' timethatone end of,

The heat-generator Gfof the typerep'resentedin Fig.3 isplaced above,a basin .7, constantly supplied with water by a tube 7; This generatoris' placed near the door 8, closing a tunnel, the walls ,9 of-which are formed of materials-of the same mineral substance. Beneath the bottom "fines 10' are v"formed,

through whichthe'coldouter airpasses. In

the part of the bottom'l'under these fines a bundle of metal wires 11 are arranged, these \vi res beinggood conductors of electricity and united outside thefurnace by a terminal '12 for taking the current.- Another bundle of *wires=13, united byanother terminal .14, is

located in thecentralpart of thethick-ness of the archof the furnace. The other Iwalls 15-'o the-furnace are constructed of insulat mg refractory material. Theitube 5-com- 'municates .Withan external reservoir 16, containin'gpetroleum orfother hydrocarbon,.and

terminates in the openings 2 inthe generator G. The-door 8 is providedwithfair-openings for keeping up combustion. Q'Ihe hydrOoar:
